In this way, it is possible to prevent the wire from detaching from the wire accommodating slot 1511 to keep the operation of fan 2 from being affected. The surfaces of two sides of the wire accommodating slot 1511 abut against the surface of the chip circuit board facing the shielding 15 to prevent the chip circuit board from disengaging from the chip slot.

In this embodiment, as the length of a side of the wiring securing block 1514 parallel to the connector body 10 is shorter than the length of a side of the wire accommodating slot 1511 parallel to the connector body 10, there is enough space on the two sides of the wiring securing block 1514 for the wire to pass through.

FIG. 19 is a use state diagram of a fan connector of the seventh embodiment of the present disclosure. As shown in the figure, the fan connector 1 of this embodiment is different from that of the sixth embodiment in that the shielding 15 further comprises a protection part 152 disposed on one side of the anti-disengaging part 151 away from the connector body 10. The protection part 152 comprises a plurality of ventilation holes 1521 corresponding to an air outlet 21 of the fan 2, allowing the airflow from the air outlet 21 of the fan 2 to flow through the plurality of ventilation holes 1521 to keep the fan 2 under regular operation. The tallness of the protection part 152 is 0.3 to 1 times the tallness of the fan 2. In this embodiment, the protection part 152 is shorter than the fan 2, and the tallness of the protection part 152 is 0.4 times the tallness of the fan 2, so the protection part 152 does not completely cover the air outlet 21 of the fan 2. The protection part 152 of this embodiment could prevent external objects such as insects and wires interfering with the operation form entering the fan 2. The protection part 152 is integrally formed with the anti-disengaging part 151 to one piece.

FIG. 20 is a use state diagram of a fan connector of the eighth embodiment of the present disclosure. As shown in the figure, the fan connector 1 of this embodiment is different from that of the seventh embodiment in that the protection part 152 is as tall as the fan 2. So that the protection part 152 could entirely cover the air outlet 21 of the fan 2, and could keep user's hands from touching fan blades for safety.

In summary, the present disclosure proposed a fan connector in which a chip is soldered onto the circuit board as a chip circuit board, which is directly inserted into the chip slot of the connector body when the fan connector is in use. The chip circuit board is easy to be inserted into the connector body, and the connective pads of the chip circuit board can be stably connected to the corresponding chip terminals, thereby the reliability of the fan connector is increased. Also, the shielding prevents the chip circuit board from disengaging from the chip slot, which also improves the reliability of the fan connector. The shielding comprises a protection part, which prevents external objects such as insects and wires from entering the fan and keep user's hands from accidentally touching fan blades.
